99.95% yoyera tungsten elekitirodi makampani
Elekitirodi yoyera ya tungsten ndi electrode yomwe imagwiritsidwa ntchito powotcherera mpweya wa tungsten inert (TIG), yomwe imadziwikanso kuti gas tungsten arc welding (GTAW). Ma elekitirodi a tungsten oyera amapangidwa kuchokera ku 99.5% tungsten yoyera ndipo nthawi zambiri amakhala ndi mitundu yobiriwira. Amadziwika kuti amatha kupirira kutentha kwambiri komanso kupereka ntchito yokhazikika ya arc.
Ma elekitirodi oyera a tungsten amagwiritsidwa ntchito powotcherera zinthu zomwe zimafuna malo osatulutsa okosijeni, monga aluminium ndi magnesium alloys. Popeza amapanga arc yolunjika komanso yolondola, ndi oyeneranso kuwotcherera zida zowonda kwambiri.
Ma elekitirodi a tungsten oyeretsedwa ndi osavomerezeka pa ntchito zowotcherera zomwe zimafuna milingo yaposachedwa kwambiri kapena zida zowotcherera zomwe zimapanga zigawo zokhuthala za oxide, chifukwa zimatha kuipitsidwa ndipo zimatha kuyambitsa kugwedezeka kwa arc.
Mwachidule, ma elekitirodi oyera a tungsten amapangidwa makamaka kuti agwiritse ntchito kuwotcherera kwa TIG pomwe malo osakhala oxidizing komanso kuwongolera kwa arc ndikofunikira. Ndi abwino kuwotcherera aluminium, magnesium ndi zinthu zina zopanda chitsulo, zomwe zimawapangitsa kukhala chida chamtengo wapatali pamakampani owotcherera.
Ma elekitirodi a Tungsten omwe amagwiritsidwa ntchito powotcherera TIG nthawi zambiri amapangidwa kuchokera kumtundu wapamwamba wa tungsten, ndikuwonjezera zinthu zina zochepa kuti ziwongolere magwiridwe antchito awo. Zigawo zodziwika bwino za tungsten ma elekitirodi ndi awa:
1. Ma Electrodes Oyera a Tungsten: Ma elekitirodi awa amapangidwa ndi 99.5% tungsten yoyera ndipo nthawi zambiri amakhala ndi mitundu yobiriwira. Ndioyenera kugwiritsa ntchito kuwotcherera komwe kumafunikira malo osakhala oxidizing, monga kuwotcherera aluminium ndi ma aloyi a magnesium.
2. Ma Electrodes a Tungsten: Ma electrode awa ali ndi thorium oxide yosakanikirana ndi tungsten (nthawi zambiri 1-2%). Nthawi zambiri amakhala amitundu ndipo amakhala ndi nsonga yofiira. Ma electrode a thorium amadziwika chifukwa cha kuyambika kwawo kwabwino kwambiri komanso kukhazikika, kuwapangitsa kukhala oyenera kugwiritsa ntchito zida zambiri zowotcherera.
3. Ceramic tungsten electrode: Elekitirodi ya Ceramic ili ndi cerium oxide (nthawi zambiri 1-2%) ndi tungsten. Mtundu wawo nthawi zambiri umakhala walalanje. Ma elekitirodi a Ceramic ali ndi kukhazikika bwino kwa arc ndipo ndi oyenera kuwotcherera kwa AC ndi DC, kuwapangitsa kukhala oyenera kugwiritsa ntchito zowotcherera zosiyanasiyana.
4. Electrode ya tungsten yapadziko lapansi yosowa: Elekitirodi yapadziko lapansi yosawerengeka imakhala ndi lanthanum oxide yosakanikirana ndi tungsten (nthawi zambiri 1-2%). Mtundu wawo nthawi zambiri umakhala wabuluu. Ndodo zowotcherera za Lanthanum zili ndi zida zabwino zoyambira ndi kukhazikika, ndipo ndizoyenera kuwotcherera kwa AC ndi DC.
5. Zirconium tungsten electrode: Zirconium electrode ili ndi zirconium oxide yosakanikirana ndi tungsten (kawirikawiri 0.8-1.2%). Mtundu wawo nthawi zambiri umakhala wofiirira. Ma elekitirodi a Zirconium amadziwika chifukwa chotha kukana kuipitsidwa ndipo amagwiritsidwa ntchito kwambiri pakuwotcherera kwa AC aluminium ndi magnesium alloys.
Mtundu uliwonse wa ma elekitirodi a tungsten uli ndi mawonekedwe ake omwe amaupangitsa kukhala oyenera kugwiritsa ntchito kuwotcherera kosiyanasiyana. Kusankhidwa kwa ma elekitirodi kumatengera zinthu monga mtundu wa zinthu zomwe zimayenera kuwotcherera, kutenthetsa pakali pano, komanso zofunikira pakuwotcherera.
